Answer:

The area of the hexagon is 108 cm².

Step-by-step explanation:

Consider the below figure attached with this question.

From the below figure we get

Length of rectangle = 12 cm

width of rectangle = 5 cm

It is given both triangles are identical.

Base of each triangle = 12cm

Height of each triangle = (13-5)/2 = 4 cm

Area of rectangle is

[tex]Area=length\times width=12\times 5=60[/tex]

Area of rectangle is

[tex]Area=\frac{1}{2}\times base\times height[/tex]

[tex]Area=\frac{1}{2}\times 12\times 4=24[/tex]

Area of one triangle 24 cm². So, area of both triangle is

[tex]2\times 24=48[/tex]

Area of hexagon = Area of rectangle + Area of both triangles

                            = [tex]60+48[/tex]

                            = [tex]108[/tex]

Therefore, the area of the hexagon is 108 cm².

By finding the areas of the rectangle and the two triangles separately and adding them together, we determine that the area of the hexagon is 125 cm².

To find out the area of the hexagon, you would need to find the areas of the rectangle and the triangles separately, and then add them together. The rectangle's area can be calculated easily using the formula for the area of a rectangle: Length x Breadth.

Assuming the rectangular part length to be 13cm and breadth to be 5cm, area of rectangle = 13cm x 5cm = 65cm².

The two triangles appear to be right triangles. You can use the formula for the area of a right triangle: 0.5 x Base x Height.

Assuming the base and height of the triangles to be 12cm and 5 cm, therefore the area of one triangle is 0.5 x 12cm x 5cm = 30cm². Since there are two of these triangles, their combined area = 2 x 30cm² = 60cm².

Finally, combining the areas of the rectangle and triangles equals the area of the hexagon: 65cm² + 60 cm² = 125 cm².

The area of the hexagon is

125 cm²

Answer:

Step-by-step explanation:

p = peaches, m = mangos

1.75p + 1.50m = 22

m = p + 6

1.75p + 1.50(p + 6) = 22

1.75p + 1.50p + 9 = 22

1.75p + 1.50p = 22 - 9

3.25p = 13

p = 13 / 3.25

p = 4 <====== she bought 4 peaches

m = p + 6

m = 4 + 6

m = 10 <===== she bought 10 mangos

check...

1.75p + 1.50m = 22

1.75(4) + 1.50(10) = 22

7 + 15 = 22

22 = 22 (correct)

The number of peaches and the number of mangos that Savannah bought

are 4 and 10 respectively.

The variable use to write the equation is x and it is the number of peaches

Savannah and her children bought

let

the number of peaches Savannah and her children bought = x

Therefore

the number of mangoes Savannah and her children bought = x + 6

The total worth of what they bought = $22

Therefore,

1.75x + 1.50(x + 6) = 22

1.75x + 1.50x + 9 = 22

3.25x + 9 = 22

3.25x = 22 - 9

3.25x = 13

x = 13 / 3.25

x = 4

Therefore,

number of peaches bought = 4

number of mangoes bought = 4 + 6 = 10

Answer:

Admission fee charged = $3

Cost of each ride = $10

Step-by-step explanation:

Let admission fee charged by amusement park in dollars be =[tex]x[/tex]

Let cost of each ride in dollars be =[tex]y[/tex]

Given:

Admission plus four rides cost $22

If each ride cost in dollars = [tex]y[/tex]

Cost of 4 rides in dollars will be  = [tex]4y[/tex]

So, the total cost in dollars will be given as =[tex]x+4y[/tex]

So, we have

[tex]x+4y=22[/tex]

Admission plus seven ride cost $31.

If each ride cost in dollars = [tex]y[/tex]

Cost of 7 rides in dollars will be  = [tex]7y[/tex]

So, the total cost in dollars will be given as =[tex]x+7y[/tex]

So, we have

[tex]x+7y=31[/tex]

So, we have the system of equation as:

A) [tex]x+4y=22[/tex]

B) [tex]x+7y=31[/tex]

Solving the system by elimination method.

Eliminating [tex]x[/tex] by subtracting equation A from B.

   [tex]x+7y=31[/tex]

- [tex]x+4y=22[/tex]

   -       -      -  [Sign of each term of subtract-ant gets reversed]

-----------------------------

      [tex]3y=9[/tex]

Dividing both sides by 3.

[tex]\frac{3y}{3}=\frac{9}{3}[/tex]

∴ [tex]y=3[/tex]

Plugging in [tex]y=3[/tex] in equation A.

[tex]x+4(3)=22[/tex]

[tex]x+12=22[/tex]

Subtracting both sides by 12.

[tex]x+12-12=22-12[/tex]

Answer:

C

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

To obtain this form use the method of completing the square

Given

y = 2x² - 8x + 9

The coefficient of the x² term must be 1, so factor out 2 from 2x² - 8x

y = 2(x² - 4x) + 9

To complete the square

add/ subtract ( half the coefficient of the x- term)² to x² - 4x

y = 2(x² + (- 2)x + 4 - 4) + 9

   = 2(x - 2)² - 8 + 9

   = 2(x - 2)² + 1 → C

The given quadratic equation y = 2x^2 - 8x + 9 can be rewritten into vertex form by completing the square, resulting in y = 2(x - 2)^2 + 5.

The given equation y = 2x2 - 8x + 9 can be rewritten in vertex form by completing the square for the -8x term. The vertex form of a quadratic equation is y = a(x - h)2 + k, where (h,k) is the vertex of the parabola.

First, we need to divide the coefficient of the x term, which is -8, by 2 to get -4. Then, we square this result to get 16.

This should be inserted into the equation to complete the square, however, we must also take it out again in order to not change the equation. The new equation will be y = 2(x2 - 4x + 16) - 2*16 + 9 = 2(x - 2)2 + 5.

The correct answer then is B. y = 2(x - 2)2 + 5

The correct mathematical expression for eight times the difference of 4 and a number is 8(4 - n), where 'n' is the variable representing the number.

The expression that represents eight times the difference of 4 and a number can be written as 8(4 - n), where 'n' represents the number in question. In this expression, '4 - n' is the difference between 4 and the number, and by multiplying this difference by eight, we are following the order of operations where the subtraction within the parentheses is performed first before the multiplication.

Answer:

y = -2/3 x + 1/3

Step-by-step explanation:

Use the slope-intercept linear formula: y = mx + b

x and y represent point on the line

m is the slope

b is the y-intercept

The equation of the line requires "m" and "b". We already have "m".

Substitute point (-4, 3) and slope -2/3 into the formula. x=-4; y=3; m=-2/3. Find b by isolating the variable.

y = mx + b

3 = (-2/3)(-4) + b   Simplify

3 = 8/3 + b     Subtract 8/3 from both sides

b = 1/3

Put b = 1/3 into the formula.

y = -2/3 x + 1/3

It is easy to see if a set of ordered pairs is a relation or a relation that is a function.

If all the points are distinct, then you just have to look at the [tex]x[/tex]-coordinates.

If all the [tex]x[/tex]-coordinates are different, then it is a function. Otherwise, it is a just a relation.

Answer:

b.) Triangle 7 has a 40 degree angle and a 35 degree angle. Triangle 8 has a 40 degree angle and a 105 degree angle.

Step-by-step explanation:

b.) triangle 7's 3 angles: 40° , 35° and 180° - 40° - 35° = 105°

    triangle 8: 40° , 105° and 180° - 40° - 105° = 35°

they have all 3 corresponding angles congruent, triangle and triangle 8 is similar (AAA)

Answer:

b.) Triangles 7 and 8 are similar.

Step-by-step explanation:

If triangles have the same angle measurements, they are similar

If we have two angles, we can find the third by using the equation 180 (total of all angles in any triangle) - angle 1 -angle 2 = angle 3.

Let's set up this value with values from triangle 7.

180-40-35=angle 3

105=angle 3

Thus, the angle measurements of triangle 7 are 35, 40, anf 105.

Let's set up the same equation with value for triangle 8.

180-40-105=angle 3

35=angle 3

Thus, the angle measurements of triangle 8 are 35, 40, anf 105, the same as those of triangle 7, meaning the two triangles are similar.

Step-by-step explanation:

The first simplification we can make is to replace 6^0 with 1.

The first rules of exponents we can apply are ...

  (a·b)^c = a^c·b^c . . . . . . similar to the distributive property

  (a^b)^c = a^(b·c)

This reduces your expression to ...

  [tex](2^8\cdot 3^{-5})^{-2}\cdot\left(\dfrac{3^{-2}}{2^3}\right)^4\cdot 2^{28}=2^{8(-2)}\cdot 3^{-5(-2)}\cdot\dfrac{3^{-2(4)}}{2^{3(4)}}\cdot 2^{28}\\\\=2^{-16}\cdot 3^{10}\cdot\dfrac{3^{-8}}{2^{12}}\cdot 2^{28}[/tex]

Now we can apply another two rules of exponents:

  (a^b)(a^c) = a^(b+c)

  1/a^b = a^-b

Using these, we have ...

  [tex]=2^{-16-12+28}\cdot 3^{10-8}\\\\=2^0\cdot 3^2\\\\=1\cdot 9=9[/tex]

Answer:

Amount of juice left over is 1.5 cups.

Step-by-step explanation:

Given:

Amount of juices Grace has = 6 cups

Number of friends = 8

She divides the juice equally among her friends.

Now we will first find Amount of juice each friend will have.

Amount of juice each friend will get can be calculated by dividing Amount of juices with total number of friends.

Framing in equation form we get;

Amount of juice each friend will have = [tex]\frac{6}{8}= \frac{3}{4}\ cups \ \ \ OR \ \ \ \ 0.75\ cups[/tex]

Number of friends who do not drink = 2

Amount of juice left will be equal to Number of friends who do not drink multiplied by Amount of juice each friend will have.

Framing in equation form we get;

Amount of juice left = [tex]2\times \frac{3}{4} = \frac{3}{2} \ cups \ \ \ \ OR \ \ \ \ 1.5\ cups[/tex]

Hence Amount of juice left over is 1.5 cups.
